Questions: 10 | Attempts: 316 | Last updated: Mar 21, 2023

Sample Question
Artistic depictions of the sun usually have rays emanating from a round disk. Why is the sun often drawn this way?

It's only an abstract symbol for the sun.

You think that you see rays from the sun because your eye is not a perfect camera.

You can see light rays that travel sideways if they are very bright.

It's the solar corona: Jets of hot gas that shoot out from the sun.

The earth's atmosphere bends sunlight and makes radial streaks.
